Fool on street is landing (9)

I believe the answer is:

stairhead

'is landing' is the definition.
(I've seen this before)

'fool on street' is the wordplay.
'fool' becomes 'airhead' (I've seen this before).
'on' says to put letters next to each other.
'street' becomes 'st'.
'airhead' after 'st' is 'STAIRHEAD'.

(Another definition for stairhead that I've seen is " landing after a flight".)

I've seen this clue in The Times.
